OFFICE ALLAN JONES, OF TRENTON, NEW JERSEY, ASSIGR'OR 'I'O ROLLER BEARING COM- rm OF AMERICA, TREN'ION, NEW JERSEY, A. CORPORATION OF NEW JERSEY manna Application filed February 19, 1980. Serial- No. 429,800.

This invention relates to a feeder which is designed and adapted to feed artlcles such as roller bearings to a grinding or fimshmg machine.

The principal object of the invention 1s toprovide a feeder of the indicated character of simple and practical construction, and one which is continuous in operation.

. The nature of the invention and 1ts'd1s- 1 tinguishing features and advantages will apr when the following specification is read in connection with the accompanying drawing in which igure 1 is it vertical sectlon of the feeder ll embodying the features of the invention, the

section belng taken on the line 11 of Figure 2 Figure 2 is a horizontal section taken on the line 2-2 of Figure 1;

a0 Figure .3 is an "enlarged fragmentary section taken on the line 33 0 Figure 4;

Figure 4 is an enlarged fraigmentary section taken on the line 44 of igure 2.

Referring now more particularly to the drawings, it will be apparent that the feeder includes a rotor or disk 10, secured in an' practical manner to the upper end of a sha t 11 supported for rotation in any suitable manner. In the present instance the shaft 11 is vertically disposed and the lower end there'- of is'received in a bearing 12 on a base 13. The rotor or disk is of stepped construction having a continuous circumferential upper surface 14 below the major upper flat sur- 18 extending tangentially with respect to the circumferential edge-or periphery of the disk 10. A rigid feed tube 19 is detachably connected as at 20 with an enlargement 21 shown in the drawings, the shaft is rotated face 15 thereof. A stator shell or circular receive and guide articlesv delivered thereto .stepped construction rotatable on a vertical 13. The shell 16 has a discharge passageway 1 throu h which the passageway 18 extends, so as to orm a continuation of the passageway 18. I f

The disk shaft 11 may be rotated in any suitable manner at the desired speed. As

by an electric motor 22 and driving means between the motor shaft and the shaft 11, said, means being designated in general by the reference numeral 23. l I

From the foregoing it willbe apparent that when articles, such as roller bearings of cylindrical form, are placed on top of the disk 10, they will be caused to move outwardly by centrifugal force imparted by the rotational movement of the disk 10. The roller bearings are designated 24. As the bearings 24 are moved outwardly by the centrifugal force imparted by the disk 10 .the will encounter the shell 16.. Some of the bearings 24 will fall onto the circumferential surface 14 and be directed into the entrance end of the passage 18 one after the other. In this connection it is to be understood that the disk 10 will rotate in a counter-clockwise direction, as seen in Figure 2. The bearings 24 are guided through the passageway 18 into the tube 19 in end to end relation in contact with each other and are forcibly fed from the'tube 19 into the presence of suitable rotary grinding or finishing elements constituting appurtenances of the grinding or finishing machine, not shown in the drawings. Claims: I

1. In a feeder, the combination of a disk rotor of stepped construction, a stator shell surrounding said rotor, said shell having a discharge passageway extending tangentially Q with respect to the periphery of the rotor, to

from the rotor by the rotational movement of the rotor.

.2. In a feeder, the combination of a disk of axis, a stationary shell surrounding said disk, said shell having a discharge passageway'extending tangentially with respect to the pe riphery of said disk, to receive and guide articles delivered thereto from the top of said disk by the rotational movement of the disk.

2* lessees 3. In a feeder, the combination of a disk rotatable on a vertical axis, said disk having a continuous circumferential upper surface below the major upper surface of the disk, a stationary shell fittin around the circumferential edge of the dis said shell having a discharge passageway extending tangentially with respect to said ed e to receive and gulde articles delivered t ereto from said circumferential upper surface of the disk by the rotational movement of the disk ALLAN H JQNES.
